5G NG-RAN: Architecture and Operations

The cellular industry is gearing up for 5G. The industry is planning to support a variety of new and exciting services such as Augmented Reality (AR)/Virtual Reality (VR), hologram videos, and self-driving cars. Such services require a wide range of network capabilities to support a variety of consumer devices and Internet-of-Things (IoT) devices. This 5G course takes an in-depth look at the 5G Next-Generation Radio Access Network (NG-RAN) architecture and major operations that enable a 5G network to support the target 5G services. The 5G course first introduces new services and associated network performance requirements. Various aspects of the NG-RAN such as new protocols, Dual Connectivity, gNB-Central Unit, and gNB-Distributed Unit, and cloud-RAN or virtualized RAN. Key New Radio (NR) air interface specifics such as massive MIMO, numerology, and flexible frame structure are illustrated. Network acquisition, random access, and connection setup are described. Registration and session setup are discussed along with a close look at network slicing. The data transfer in both downlink and uplink is described. Mobility in connected, inactive, and idle modes is discussed. Finally, the status of 5G in in the industry is summarized.
